#2668: GRHydro: work around Intel 19 compiler issue
Reporter: Roland Haas Status: new Milestone: ET_2022_11 Version: ET_2021_05 Type: bug Priority: major Component: EinsteinToolkit thorn
The intel 19 compiler and newer apparently miscompile GRhydro’s HLLE code when MHD is enabled. This results in either a SEGFAULT of con2prim failures. This has been in the ET tests since around 2021 (it shows up in the ET_2021_05_v0 release tests).
Pull request [https://bitbucket.org/einsteintoolkit/einsteinevolve/pull-requests/18%5D(htt...) provides a workaround. With it the affected tests pass, see eg qb an supermuc on [http://einsteintoolkit.org/testsuite%5C_results/index.php%5D(http://einstein...)
